Product Overview


The compression copper pipe fittings are high-performance plumbing components tailored specifically for solar collector plumbing systems, designed to establish secure, leak-free connections between copper pipes and plumbing networks without the need for welding. Produced by Solaraven, these brass compression fittings integrate robust structural design with user-centric functionality, making them a preferred choice for HVAC and plumbing applications where reliability, efficiency, and durability are non-negotiable. Whether utilized in flat plate or heat pipe solar collectors, these fittings ensure unobstructed fluid flow while withstanding extreme pressure and temperature variations, delivering consistent performance for both residential and commercial solar water heating setups.


Weld-Free Compression Copper Pipe Fittings


Key Features


Reliable Sealing Performance in Extreme Conditions

Equipped with a metal-to-metal ferrule seal or combined with elastic sealing rings (e.g., rubber or fluororubber), the compression copper fittings achieve a robust sealing effect that effectively prevents leakage even under high-pressure environments up to 800 bar. Their engineered design maintains optimal structural integrity in both low and high-temperature settings, making them perfectly suited for solar systems exposed to harsh outdoor weather fluctuations.


Strong Vibration Resistance & Long-Term Durability

The innovative fitting structure—incorporating double-edged ferrules or elastic seals—efficiently absorbs pipeline vibrations, significantly reducing the risk of loosening over prolonged use. This feature makes the copper pipe fittings ideal for rugged operating conditions such as construction machinery hydraulic systems or solar collectors installed in high-wind areas, ensuring extended service life without compromising performance.


Tool-Free Assembly & Hassle-Free Maintenance

Unlike traditional welding-dependent fittings, these plumbing copper fittings adopt a ferrule connection design that enables quick, straightforward assembly—no specialized tools or professional welding skills required. This saves valuable time and labor costs during installation. Selected models are equipped with functional nuts and built-in pre-loaded bodies to prevent overtightening, further enhancing assembly efficiency and reliability. Disassembly and maintenance are equally convenient, supporting repeated use without affecting the fitting’s sealing performance.


Premium Brass Material Advantages

Crafted from high-grade brass, the compression copper pipe fittings offer exceptional corrosion resistance, strong mechanical strength, and superior machinability. This material versatility allows them to adapt to various fluid environments, including water, oil, and gas, extending their application beyond solar collector plumbing. The brass construction also ensures resistance to rust and degradation, prolonging the fittings’ service life in demanding conditions.


International Standardization & Interchangeability

Compliant with international standards such as ISO, these brass compression fittings are fully interchangeable with traditional plumbing fittings. This interchangeability facilitates seamless integration into existing HVAC systems, solar water heater setups, or plumbing networks, eliminating compatibility issues and reducing replacement costs for users.
